Patent CA-2069214-C (CA)
Title: Reconfigurable air bag firing circuit
Inventor: WHITE CRAIG W
IPC: G01P21/00
Filed: 1992-05-22
Granted: 1996-12-17
Abstract: An air bag firing circuit comprises a firing path which includes in series a safing sensor, a squib, and a FET operated under microprocessor control  in response to the output  of  an  electronic  crash  sensor.    A  power  supply maintains a known voltage across the firing path sufficient to explode the squib upon simultaneous "closure" of both the safing sensor and the FET operated by the microprocessor in response to crash sensor output.  Normally, upon detection of a failure in the electronic crash sensor,  its supporting electronics,  or the FET actuated in response thereto,  the microprocessor reconfigures the firing threshold of the safing sensor, as by applying a current to its integral test coil to increasingly bias the sensor's inertial mass away from its switch contacts.  However, if a failure of the safing sensor is detected, reconfiguration of its threshold is inhibited notwithstanding the failure of other circuit components to prevent inadvertent deployment of the air bag.   Once the safing sensor is reconfigured, the microprocessor turns on another FET to pull one side of the squib to ground, thereby removing the inoperable FET from the firing path and ensuring continued protection of the vehicle passengers until  the sensor is serviced or replaced.

Abstract: Un système de commande de déclenchement destiné à un fonctionnement vernier sûr d'un condensateur (TCSC) (30) commandé par thyristor en série avec une ligne de transmission (24) utilise un déclenchement à phase commandée basé sur la tension contrôlée du condensateur et sur le courant du secteur. Le fonctionnement vernier du système TCSC (20) est assuré par prédiction d'un angle de déblocage survenant pour commuter le circuit de commutation (32) afin de faire passer une impulsion de courant de dérivation du thyristor. L'impulsion de courant produit une composante de tension de décalage alternatif au niveau du condensateur en série (30), en plus de la composante de tension normale, chaque impulsion de courant modifie la tension du condensateur proportionnellement à la valeur intégrée de l'impulsion de courant. Le système TCSC (20) répond de manière prompte à une commande de décalage provenant d'une unité de commande à plus haut niveau (86), et il commande avec précision le travail sur les thyristors de dérivation (36a, 36b) afin de réduire au minimum les dommages causés aux thyristors, et empêche la dérive de la tension des condensateurs en lui interdisant de s'éloigner d'une valeur consigne désirée lors des perturbations sur le courant de secteur.

Abstract: Residua can be upgraded by first partitioning a hydrocracked residua into a vapor fraction and a liquid fraction. The vapor fraction is hydrotreated forming a first hydrotreated product. The liquid fraction is partitioned into a residua fraction and a light liquid fraction. The light liquid fraction can be hydrotreated or hydrocracked to form a hydroprocessed product. The hydrotreated product and the hydroprocessed product are then combined forming a substantially upgraded synthetic crude product refinable as a routine crude in a refinery into products that meet stringent specifications. In particular, residua can be upgraded to make a quality jet fuel fraction and a naphtha fraction containing less than 1 ppmw sulfur and nitrogen.

Abstract: A method of applying a label to a container which includes an intermediate portion of the side wall thereof which has an annular curved surface wherein the vertical height of the portion having a curved surface is a minor portion of the entire height of the container. A narrow rectangular label of shrinkable material is first provided with one or more longitudinally extending strips of adhesive extending intermediate the longitudinal edges of the label at the area of the label which is to contact the portion of greatest diameter on the curved portion of the container. The strip of adhesive material is shorter than the length of the label so that the adhesive material does not contact the overlapping edges of the label. An adhesive is applied to the trailing edge of the label only and the label is wrapped about the compound curved portion with the adhesive strip engaging the curved portion of the container at the area of greatest diameter. The edges of the label are overlapped and bonded and the overlapped label is then shrunk into position by moving the container and label through an oven. The curved portion of the container may have a compound curvature.

Granted: 1999-05-04
Abstract: A method of forming a template of an image of an object includes the steps of: detecting occurrences of at least one feature type within the image which meet a respective criterion; for each such occurrence, determining a feature position which is a point within the image at which the occurrence of the feature type is to be considered as being located; and constructing a structural mesh of links between the feature positions. A method is also disclosed of forming a template derived from a plurality of templates formed from respective images of different members of the class of objects and combining the templates to form a generalised template. In particular the templates are combined using a genetic algorithm. The invention provides a method of forming a template from one or more images which does not rely on a priori assumptions about the salient features of the object for which a template is to be obtained.

Abstract: A maximum-likelihood sequence estimator (MLSE) with a variable number of states.  A channel response estimator calculates channel responses from a received signal having a predetermined burst length and a reference signal. A controller checks the latest (L-th) response having a larger power than a predetermined threshold value of the channel responses and determines the L number of effective channel responses having the larger power.  A Viterbi equilizer with a variable number of states executes a maximum-likelihood sequence estimation on the basis of the trellis with M(L-I) states (M is a multi-value number of a modulation signal) using the L number of effective channel responses.  The MLSE is operated with the minimum number of states every burst to reduce an average processing amount without degrading characteristics and to achieve a low consumption power of receivers.
